I'm glad you brought that up. I do think we have the expressiveness in OWL (and in Description Logics, generally) to model term alignment (equivalent classes/properties, inverse roles, value restrictions, etc..) as a seperate ontology This would refer to (and therefore owl:import) the HCLS-Experiment ontology ( to ground the mapping semantically not just for annotation purposes ). You can then either have the instance graphs that depend on the Gel/BOSS associate with this term mapping (expressed as an OWL ontology) with rdfs:isDefinedBy, or have the Gel ontology import this lingua franca ontology directly. Just some thoughts. Not a trivial proposition, but we have sufficient expressiveness to capture this kind of web ontology management pattern (and others like it). instance Graph / other ontology | V BOSS | V Concept Mapping Ontology (an o3:Profile) | V HCLS-Experiment Ontology Chimezie Ogbuji Lead Systems Analyst Thoracic and Cardiovascular Surgery Cleveland Clinic Foundation 9500 Euclid Avenue/ W26 Cleveland, Ohio 44195 Office: (216)444-8593 ogbujic@ccf.org
